' rnntrrcarro TIRE;

Be it known that I, FRED B. PFnIrrER, a

Icitizen of the United States, residing atv Akron, inthe county of Summit and State of Ohio, have invented va'neW and useful Pneumatic Tire, of which the following'is a specification. v

lt is the object of this invention to provide a casing for a pneumatic tire, lwhich Will possess extreme flexibility, and, at the sametime, be practically puncture-proof.

rlhe invent-ion aims to improve generally and to enhance the utility ofldevices of that type to which the invention appertains.

lilith the above and otherobjects in view, which Will appear as the description proceeds, the invention resides in the combina--. ltion and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that, Within the scope of What is claimed, changes in the precise embodiment of the invention shown canbemade Without de} 3arting from v the spirit of the invention.

" ln the accompanying drawings Figure l shows in transverse section, a

device constructed in accordance with the invent-ion; Figure 2 is a top plan showing a portion of one of the strips; Figure 3 is a fragmental plan showing a portion of another ofthe strips; Figure 4l is av fragmental planshowing a modication-g land Figure `5 is a sectional detail enlarged from Figure l. l

4The numeral l denotes thecasing of la Vehicle tire. .ln the casing l are embeddedv flexible metal strips 2 and rThe strip 2 hasslits Il extendinoY di'aUena-llv ofthe str1 i.

a h J l Slits 5 are fashioned in the strip 3 and ex-y tend diagonally thereof, the slits l and of the respective strips being 'located at an angle to each other.A At their ends, the slits lfl desired, a layer `of elastic material 7,

material entering the slits 4l and 5 and the enlargements 6. In this connection 1t is to Specification of Letters Patent.l

be'observed that'the slits 4Q, and-'5 maylbei of any desired lWidth.`

shall have extreme `iiexibility along its' strips from' thelongitudinal edges thereof,

In ease it is desired that the tirecasing 'Patented aegis-1922.5. Application filed November 2.8, 1919,. Serial N30. 340,995. i i

It is obvious that a tire casing constructed in accordance With-theinventionas'above de-l scribedwill possess resiliency and strength,v

and, at the same time, will be practically puncture proof,

Having thus described lthe invention, What lis claimed is'- f l. In a device` of' the vclass described, "a casing; and superposed metal strips embedded in the casing, each; strip having :g

kdiagonal slits, 'all of which are' located entirelywithin the strip,the,s lits`of one strip I I being disposed at an yaiigleito the slitslofanl adjoining strip.
